the teacher still didn't know ___
问题描述:
the teacher still didn't know ___
A:how you work hard at English
B:how did you study English well
C:how you improved your English
答
C
题意:老师还不知道你是怎样提高你的英语的.
宾语从句中要用陈述语序,B为倒装语序,先排除
A应改为 how hard you worked at English; 从此可以看出A一方面是语序不对,同时其用的时态也不对,应用过去时而不用一般现在时,因为主句的谓语是一般过去时,主从句时态要保持一致.
